PETER N. BARDO, OF NEVPORT, KENTUCKY, ASSIG-NOR lO THE BOURBON COPPER AND BRASS VORKS, OFBCINCINNAT, OHIO.

STILL.

SPECIFICATION forming part of Letters Patent No. 291,833, dated January 8, 1884. Application filed July 9, 1853. (No'inodelll To @ZZ whom, if, may concern.-

Be it known that I, PETER N. BARDO, a citizen of the Unit-ed States, residing at Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Stills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to certain improvements in that class of' stills for the distillation of spirituous liquors from beer, mash, or wort, known as continuous stills,77 and the still, briefly described, consists in a series of vertically-arranged chambers, each provided with boiling-pipes and conduits leading from the one above to the one next below with suitable induction, steam, low -wine, and beer pipes, and with suitable eduction, vapor, and slop pipes. v

The novelty consists in the construction and combination of the parts, as will bc herewith set forth and specifically claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved still,with one side removed to show the construction and relative arrangement ot' the parts. Fig. 2 is a plan view ofthe bottom or steam chamber. Fig. is a vertical section through one end ofthe still. Fig. 4 is an enlarged sectional side elevation through three of the chambers ofthe still. Fig. 5 is an enlarged vertical section through one of my improved boiling or vapor pipes.

The same letters of reference are used to indicate corresponding parts in all the figures.

A A A A A represent the chambers ofthe still placed one above thc other, and of any suitable construction, with central divisiono walls, B, to form channels, as shown. The bot-toms C of these chambers are formed of sheet-copper, as is customary. The overflowpipes, leading from one chamber to the other, are represented by D, and each opens into a sealing bay or dam, E, formed by the weirsF at the ends of the channels, as indicated. T is the vapor-pipe leading from the upper chamber ofthe still. G- is the low-wine inductionpipe, II, thev limer-induction pipe opening into 5o the bay of the second chamber; and I, the

steam-induction pipe opening into the perforated drums or pipes J in the lower chamber, A. The slop-escape pipe is not here shown; but it may be of any suitable construction and opening from the bottom of the chamber.

The above parts are well known to those skilled in the art, and further description of them is unnecessary.

The application of steam to the mash in its' passage through the still serves to liberate and 6o expel the spirit, while at the same time the steam is condensed and flows out of the bottom of the still with the slop, and to more effectually cook the mash,77 as it is termed. In order to free the spirit, I employ the boiling tubes or pipes, Fig. 5, which preferably consist of a fianged tube, c, threaded at its end beneath the flange b, which said flange is about half-way of the tube, as shown.

Riveted or otherwise secured to upwardly- 7o projecting lugs ci upon the flange b is a bonnet or cap, d, preferably concavo-convex in form, and which extends over and above the mouth of the tube, as shown, but does not extend down close upon the flange. The bottom 7 5 plates, C, are perforated, and any number desired o' the tubes c are inserted through said perforations, and are clamped in place by nuts c, screwed upon their lower ends and bearing against the under sides of the plates C, as in- 8o dicated. By means of these boiling-tubes, the steam passing up through them is directed by the caps orcbonnets down on all sides evenly close to the bottom ofthe chambers, and thus effectively distributed through the mash in a 8 5 much greater degree than if a single curved tube were employed. It is also evident that these boiling-tubes or vapor-pipes are capable oi usc in different classes or constructions of stills, so that I do not limit myself to their 9o use in the construction of still'herein illustrated alone.

I am aware that heretofore bonneted vaporpipes have been proposed for stills-such, for instance, as shown -in Letters Patent N o. 185, 900, granted to Ellerhorst, January 2, 1877.

I am also aware that it has been proposed to connect vapor-pipes to their respective bottoms or partitions by means of a fianged screw end on the pipe anda screw-nut applied thereloo to below the bottom, as shown in the Patent N o. 230,333, granted .Iuly 20, 1880. I

therefore lay no claim to bonneted pipes,

broadly, nor to the particular described inanner of attaching pipes to their partitions or bottoms; but

5 That I do claim is i The herein-described boiling or vapor pipe,

consisting of the tube having the laterally-projecting iange at or near its middle7 on which are arranged the projecting lugs7 and having Io the screw-threaded portion, the bonnet or cap secured to the Said projecting lugs and arranged over the upper end of the tube, and the clamping-nut working upon the screwthreaded portion of the tube, the Whole applied to the bottoms or partitions of the stillchainbers in the manner set forth.
